Lynn,
Connect the computer *soundcard* input to the K3 rear panel Line Out,
and the computer Line out to the K3 Line IN jack. Use two stereo cables
with a 3.5mm stereo plug on each end (the plugs must be stereo even if
the signal is in only one channel - typically the left channel).
You can use VOX with no other connection to the computer, but if you do
have a serial cable batween the K3 and computer only, you can use the
PTT signal generated by the computer on the RS-232 interface. Set the
K3 menu for PTT on either DTR or RTS depending on which one your digital
application uses.
Set the K3 data mode to DATA A and you should be in business for
soundcard generated data modes. The K3 can do other forms of data mode
operation, some through the serial cable, but the copmuter applications
you mentioned only produce soundcard based data modes (DATA A in K3
terms). See the manual pages 31 and 32 for additional information.

Pardon for a dumb question, but I've hit that wall... again!
I talked to Dale at Elecraft and he suggested some of you may know the
answer as he had no experience with hooking up and making K3 work with
a computer so it will work using the sound card to have a full array
of modes, etc.
Guess I misunderstood how the K3 did this and purchased the serial to
USB cable at the time the K3 was ordered and it does the trick
relative to downloading the firmware and very well. I expected this
same cable to give me all the audio in and out plus key the rig. It
doesn't at this QTH and Dale suggested I use a serial to serial cable
which I tried and it doesn't work either. So that is where I'm at
tonight.. dead in the water, hi.
Has anyone done this and if so PLEASE share it with me?
If I'm missing something I should know please tell me too -- I can
handle it, but I've got the book memorized!
I use MixW and FLdigi on other rigs and they work fine, but the K3 is
where I'd like to do the digital modes.
Thanks, lynn W4NL
